Title: Pressure fixing device
Inventor: KARAMI YUUSUKE
IPC: G03G15/20
Filed: 1980-12-27
Abstract: PURPOSE:To reduce the size and weight of the whole fixing device and to improve its fixing property, by forming a means of applying preliminary pressure to paper before toner image transfer and another means of pressure-fixing the paper which carries the toner image after the transfer in one body. CONSTITUTION:When a calender treatment is performed by applying preliminary pressure to paper before a toner image is carried to obtain smoothness, the property of pressure fixation is improved, but providing a preliminary-pressure applying device and a pressure fixing device separately results in that the device increases in size. For this purpose, the fixing device 1 consists of a couple of rollers 5 and 6 which form a nip part for the pressure fixation of the toner image to an image carrier, and a couple of rollers 6 and 7 which form another nip part for applying preliminary pressure to an image carrier before the toner image is carried. The roller 6 performs both the fixation and preliminary-pressure application. Paper 4 is applied with preliminary pressure between the rollers 6 and 7 and, after the toner image is transferred by a transfer part 3, passes between the rollers 5 and 6 to perform pressure fixation.

Filed: 1981-11-20
Abstract: PURPOSE:To print superscript and subscript letters by a method in which a flag to make printing by biasing it toward or downward direction by 1/2 line of the base line pitch is stored with letter code and another address is generated at biased printing positions. CONSTITUTION:In the case of superscript letters, non-printing code and line feed control flag (LCF) are set in the necessary unit for the line of a page memory, and letter code to be printed and the LCF are set in the preceding line. When the LCF outputted from the page memory a flip-flop 52 is set. Since output data are prohibited by an AND gate 59 during the period of subscanning line number n=0-23, non-printing is resulted. Also, during the period of n=24-47, the output of line direction subcounter 36 and block subcounter 37 are switched to a  block select signal 116 and a bit select signal 110, a block select signal delayed  by 1/2 line is sent out, and printing is made.
